IMPROVEMENT IN APPARATUS FOR IE3 PRODUCTION 01E 950KB.-

The Schedule reams in these Letters Patent and making part of the same I, CLEAYELAND F. Dnnnnnnsnn, of New York 'city,,irr the county and :State of New York, have in vented certain Improvements in Apparatus for Producing Ozone in large quantities, of which the follow ing is a specification.

The principle'ot' my invention relates to the combination of anumber of plates or tubes of glass, silver-ed on one side, on-hy putting thereon a metal foil, or otherwise rendered a conductorof the electrical current,

soplaced in close proximity to each other as to leave only a narrow space between each for a current of atmosphericair or oxygen to pass or circulate.

The foil or silver coating 'on each plate or tube is alternately connected with the two wires of a chemical or mechanical eleotrical' machine mgalvanic battery.

The tubes or plates are arranged in a bo'x or other encasement rendered air-tightonits sirles,,and the in 'side covered with glass or other min-conducting material, to insulate the current of electricity passing through the plates, the wires connecting the alternate plates with the battery being insulated by the proper material where they-pass through the box or casing side.

The air or oxygento be ozorrized is forced or otherwise inade to pass through the case containing the plates, by a pipe made of 'a suitable material, having an exit by a pipe or otherwise attire opposite end,aiter circulating among and passing between the plates, which are electrified by a current of electricity passing from one to another, furnished by a suitable battery.

The plates may be made of metal or other suitable substance for conducting and attractingthe electricity, and insulated from contact with each other by proper non-conducting material.

Figure-1 is a side elevation. of the apparatus em bodying my invention.

' Figure 2 is an end elevation of the same, showing the supports to ihe plates.

Figure 3 is a similar apparatus made with a series of tubes, one within the'other, sih'ered or covered with foil, similar to fig. 1, only being round instead of square.

Figure 41s a longitudinal section of fig. 3'.

Figures 5 and 6 are an outside view of the casing containing the plates or tubes, which is made to con form to their shape, either round, square, or 'octagonal.

Ads the box, fig], containing the plates,- whiclr. should be coated on the insidewith some insulating material also, to withstandthe action of the ozone generated within.

B are the inlet and out-let for the air or oxygen to be passed through; which should be made of material to withstand the action of the ozone.

G are the insulated plates, siii'ered or other-wise rendered conductors on one side, kept apart from contact with each other, and supported on their longitudinal :sidcs by glass supports I), or their equiyalents. Be-

tween these the air or oxygen passes.

E are the terminals of a suitable'battery, either chemical or mechanical, their opposite wires being connected to the alternate plates.

When the air or oxygen is to be ozonized, the wires; E are connected with the battery by binding-screws F, or otherwise, and the battery set in action.

The air or o ygen, after being'suitahly preparedpis forced through the apparatus by the proper means. The electricity passing between the plates, acting on the oxygen, converts it into ozone, which, passing out of the'opposite end of the apparatus from where it entered, is to be applied as required.

I claim as my inventionl. The combination of a series of tubes or plates a conductor of electricity, or its equivalent, by being coated with metal or other substance, with a series of passages or interstices between or among them for the circulation of a current-0t air or oxygen caused to be passed therein and through, after being. suitablyprepared therefor by proper means in connection with a' galvanic or electric current, so stantially as and' for the purpose hereinbefore set. forth.

2. The combiuatiorrof the plates 0, spaces D, casing A,- inlet and outlet B, battery terminals E, hinding-screws F, supperting-insulators D for plates, substantially asar d' for'tlre-purpose hereinbefore set forth.
